Andreas Kling 2a9b6f1d97 LibJS: Move computation out of the ECMAScriptFunctionObject constructor ...

We were doing way too much computation every time an ESFO was
instantiated. This was particularly sad, since the results of these
computations were identical every time!

This patch adds a new SharedFunctionInstanceData object that gets
shared between all instances of an ESFO instantiated from some kind of
AST FunctionNode.

~5% speedup on Speedometer 2.1 :^)
